Opel labour boss expects to sign collective agreement this week

RUESSELSHEIM, Germany (Reuters) - Carmaker Opel's top labour boss said he expected to sign this week a labour agreement making wage concessions in exchange for investments, even as he clashes with management on parent PSA's <PEUP.PA> reported plans to sell parts of Opel's R&D arm.

Le Monde newspaper had reported on Tuesday that France's PSA was looking to sell part of Opel's R&D operations to help restore profitability to the loss-making unit.

Former parent General Motors <GM.N> "massively invested in this business. Now it is to be offered up for sale. That is a suicide mission," works council chief Wolfgang Schaefer-Klug told journalists on Thursday.
